CAR-COUPLING.

SPECIFICATION forming part of Letters Patent N 0. 406,970, dated July 16, 1889.

Application filed May 17,1889- Serial No. 311,149. (No model.)

To all whom, it may concern.-

Be it known that I, CROZIER T. THOMPSON, a citizen of the United States, residing at Paxton, in the county of Ford and State of Illinois, have invented a new and useful Car- Coupling, of which the following is a specification.

My invention relates to improvements in car-couplings; and it consists in certain features hereinafter described and claimed.

Figure 1 is a side view of my improved car-coupling. Fig. 2 is a vertical longitudinal section showing the link held in the drawhead in position to enter an opposing drawhead and thereby effect a coupling. Fig. 3 is a similar view showing the pin supported in an elevated position.

The coupling-pin A and the link B are of the ordinary variety, and engage each other in the usual manner. be of any desired size, and is secured to the bottom of the car at the end of the same in the usual manner. 011 the upper side of the draw-head, at the front end of the same, I provide the pin-guide D, in which the couplingpin A is mounted, as shown. The top of the draw-head is open throughout nearly its eutire length, and the sliding pinsupport E is mounted in said open portion. The said pin support is adapted to project under the coupling-pin and thereby hold it in an elevated position; and it is provided on it upper side with a stop F, which is adapted to contact with a cross-bar G on the upper side of the draw-head, so as to prevent the same being pushed too far rearward by the coupling-link in the operation of the device. The pin-support is further provided, on its under side, with a lug II, which is adapted to be struck by the end of the coupling-link in the operation of the device, as shown in the drawings, and as will be presently more fully described.

The link-holder 1 consists of a verticallydisposed block having a notch J in its front side, near its upper end, and provided on its sides, near its lower end, with the trunnions or studs K, which play in the U-sl1aped brackets L, secured to and depending from the bottom of the draw head. The linkholder plays through an opening M, in the bottom of the draw-head, and the notch J is adapted to receive the end of the link and The draw-head C may thereby hold the same in proper position for coupling.

The construction and arrangement of the several parts of my device being thus made known, the advantages and operation of the same will, it is thought, be readily understood. \Vhen it is desired to couple the cars, the pin-support is moved forward, so as to hold the pin in an elevated position, as shown in Fig. The coupling-link in then inserted in the other draw-head and engaged by the pin, the end of the link being pushed into the notch in the link-holder, as shown in Fig. 2, so as to maintain the link in a horizontal position. The two draw heads are then brought together, thereby causing the link to enter the opposing draw-head and impinge against the lug II on the under side of the pin-support, so as to push the said support rearward from under the pin and allow the said pin to fall into engagement with the link.

It will be observed that my device is composed of very few parts and is extremely si1nple in its construction. The pin-support will effectually hold the pin in its elevated position, and when pushed from under the pin by the link will move easily and readily, so that the coupling will be performed with oertainty. \Vhen the end of the link is engaged by the link-holder, it will be held in a perfectly horizontal position, so as to be guided into the opposing draw-head with precision. \Vhen the coupling has been completed and the cars have separated slightly, the link will be disengaged from the holder and the said holder will at once drop to the lower ends of the brackets L.

Having thus described my invention, what I claim, and desire to secure by Letters Patent,

1. The combination, wit-h the draw-head, of the pin-support sliding in the upper portion thereof, and provided with a stop on its upper side and a depending lug on its under side, as and for the purpose set forth.

2. The combiuatioinwith the draw-head, of the link-holder playing vertically through the bottom of the same, and provided near its upper end with a notch adapted to receive the end of the coupling-link, as set forth.

3. The combination, with the draw-head and the brackets L on the under side of the same, of the link-holder playing through the draw-head and havin g lateral studs engagin g the brackets L, andprovided with a notch near its upper end adapted to receive the end of the coupling-link, as set forth.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in presence of two Witnesses.
